litaba

UV fluorescent powder, eo hape e tsejoang e le ultraviolet photoluminescent pigment, ke pigment ea fluorescent e entsoeng ka tšepe ea calcining (zinki, cadmium) sulfide kapa li-oxide tsa lefatše tse sa tloaelehang tse nang le li-surfactants tse ngata. Bosoeu bo se nang 'mala kapa bo bobebe bo bolela leseli le bonahalang (400-800nm) le hlahang ka mebala e fapaneng ho latela mofuta le litaba tsa litšepe le li-activator tse ka har'a pigment tlas'a khanya ea ultraviolet (200-400nm) mahlaseli. Ho latela maqhubu a fapaneng a mohloli oa khanya e hlasimollang, e ka aroloa ka mebala e khuts'oane ea ultraviolet e hlasimollang ea fluorescent (excitation wavelength ea 254nm) le maqhubu a malelele a ultraviolet a excited fluorescent pigments (excitation wavelength ea 365nm). Letoto lena la lihlahisoa le bonahala le le tšoeu kapa le batla le bonaletsa tlas'a mehloli ea leseli le bonahalang, 'me le bonts'a 'mala o le mong kapa ho feta oa fluorescent tlas'a mehloli e fapaneng ea leseli la maqhubu (254nm, 365nm, 850nm). Liphoofolo tsa fluorescent li kenyelletsa litlamorao tse ikhethang joalo ka organic, inorganic, le afterglow, ka mebala e khanyang le e khanyang. Lihlahisoa tsa letoto la li-anti-counterfeiting fluorescent powder li na le mebala e mengata e fapaneng, ho kenyeletsoa bokhubelu, bopherese, botala bo mosehla, boputsoa, ​​botala, bosehla, bosoeu, boputsoa bo botala, lamunu le botsho. Metsoako e fapaneng ea mebala, phapang e sa feleng, phofshoana e khahlanong le maiketsetso ea fluorescent.Inorganic fluorescent phofo:

A. Mmala oa fluorescent o khanyang 'me o na le matla a ho koahela hantle (ntle le tlhokahalo ea li-opaque agents).
B. Likaroloana li ntle ebile li chitja, li hasane habonolo, ka bophara ba hoo e ka bang 1-10u bakeng sa 98%.
C. Ho hanyetsa mocheso o motle: Boemo bo phahameng ba ho mamella mocheso ke 600amp # 176C, bo loketseng bakeng sa ts'ebetso e fapaneng ea mocheso o phahameng. Khanyetso e ntle ea solvent, ho hanyetsa acid, ho hanyetsa alkali, le botsitso bo phahameng.
D. Ha ho phetoho ea mebala, ha ho tšilafalo.
E. Ha e chefo, ha e qhale formalin ha e futhumala, e ka sebelisoa bakeng sa ho taka lintho tsa ho bapala le lijana tsa lijo.
F. 'Mele oa' mala o ke ke oa phalla, o ka bolokang mekhoa ea ho hloekisa ha u fetola hlobo ka har'a mochine oa ente.

Phofo ea fluorescent ea tlhaho:

A. Mmala oa fluorescent oa khanya 'me ha o na matla a ho koahela, ka sekhahla sa khanya e fetang 90%. Motsoako o motle, mefuta eohle ea li-solvents tse nang le oli e ka qhibiliha, empa ho qhibiliha ho fapane, kahoo e hloka ho khethoa ho latela litlhoko tse fapaneng ha u sebelisa.
B. E le karolo ea letoto la dae, tlhokomelo e lokela ho lefshoa litabeng tsa ho fetoha ha mebala.
D. Ka lebaka la ho hanyetsa boemo ba leholimo bo bobe, li-stabilizers tse ling li hloka ho kenngoa nakong ea tšebeliso.
E Ho hanyetsa mocheso: Mocheso o phahameng oa ho mamella ke 200amp # 176C, o loketse ts'ebetso ea mocheso o phahameng ka hare ho 200amp # 176C

Sebaka sa Kopo

1. E ka sebelisoa bakeng sa ho taka libakeng tsa boithabiso, ho taka tlas'a mabone a UV. 2. Hlahisa enke e thibelang ho qhekella, pente e thibelang ho qhekella, le litlolo tse thibelang ho qhekella.
3. Etsa tlhahlobo ea boleng ba sehlahisoa
4. Theknoloji ea nako e telele ea "fluorescence anti-counterfeiting" ke theknoloji e tsoetseng pele e khahlanong le bolotsana e sebelisoang hona joale likolotong le licheleteng, e nang le lisebelisoa tse ntle tsa ho pata le tse batlang li tsebahala (li-detectors tsa chelete li atisa ho sebelisoa libakeng tsa mabenkele le libanka bakeng sa ho tsebahatsa). Theknoloji e khuts'oane e thibelang ho qhekella e sebelisa lisebelisoa tse khethehileng bakeng sa ho tsebahatsa, kahoo e na le ts'ebetso e matla ea ho thibela ho qhekella le ho pata. Fluorescent e sa bonahaleng ea ultraviolet excitation phosphor. Phosphor ena e bonahatsa fluorescence e khanyang tlas'a mahlaseli a ultraviolet 'me e sebelisoa haholo bakeng sa ho thibela ho etsa lintho tsa maiketsetso. E na le litšobotsi tsa litaba tse phahameng tsa theknoloji le ho pata mebala e metle.
